[PATCH v2 5/8] RISC-V: Add inline version of sbi_console_putchar/getchar() functions

From: Anup Patel <hidden>
Date: 2023-10-12 05:16:23
Also in: kvm, kvm-riscv, linux-riscv, linux-serial, lkml
Subsystem: risc-v architecture, the rest · Maintainers: Paul Walmsley, Palmer Dabbelt, Albert Ou, Linus Torvalds

The functions sbi_console_putchar() and sbi_console_getchar() are
not defined when CONFIG_RISCV_SBI_V01 is disabled so let us add
inline version of these functions to avoid "#ifdef" on user side.
